swap SPI_CLK_M2 and SPI_CSN0_M2
#3
Are the pins swapped vs the regular PI2 pinout? A while back I added SPI flash support together with ayufan and the SPI bus itself worked just fine, I guess I have to take a closer look at this again Smile

Edit: My latest schematic seems to have Pins23&24 correct, and at least on the SPI flash side the pins seem to be ok too...

   

   

My schematic has:

SPI_CLK_M2 - Pin23 (on PI2 header) - GPIO3_A0
SPI_CSN0_M2 - Pin24 (on PI2 header) - GPIO3_B0

And that works out with the pins on my SPI Flash as far as I can see...

If there would have been a swap between my prototyp Rock64 and the production version, I would expect the production version not having working SPI flash...
